The invention discloses a hydrogen purification drying device and an operating method thereof. The hydrogen purification drying device comprises a four-way valve, wherein a port A of the four-way valve is connected with a hydrogen inlet pipeline, a port P of the four-way valve is connected with a number-1 purification system, a port B of the four-way valve is connected with a number-2 purification system, a port T of the four-way valve is connected with a user output pipeline, a refrigeration dryer is arranged between the number-1 purification system and the number-2 purification system, and a number-1 heating device is arranged in a number-1 molecular sieve drying tower in the number-1 purification system; and a number-2 heating device is arranged in a number-2 molecular sieve drying tower in the number-2 purification system. The hydrogen purification drying device has the advantages that the structure is simplified, and the heat energy can be efficiently utilized by virtue of a built-in heating way; the water is stable to remove by virtue of cooling, and the efficiency is high; and the process gas is renewable to integrate the operating cycle and the regeneration cycle.
Description
technical field [0001] The invention relates to the technical field of hydrogen purification and drying, in particular to a hydrogen purification and drying device and a working method thereof. Background technique [0002] Hydrogen gas is used in the reduction of tungsten oxide in the production of cemented carbide, and the hydrogen gas obtained from water electrolysis needs to be dried and purified. Most of the existing drying and purification devices use molecular sieve adsorption towers. Because they can be recycled, two molecular sieve adsorption towers are generally installed in the drying and purification devices, and the molecular sieve adsorption towers can be replaced to achieve regenerative operation. However, there are many problems in the device. [0003] Such as figure 1 As shown, a hydrogen purification and drying system, the device adopts external heating and indirect cooling with chilled water generated by a refrigerator. The regeneration process requires a...
